PATENT OFFICE ASSIGNOR TO UNITED SHOE MACHINERY" CORPORATION, OFPATERSON, NEW JERSEY, A CORPORATION OF NEW JERSEY FASTENING-INSERTINGMACHINE Application filed January 15, 1926.

This invention relates to fastening-insert ing machines and isillustrated herein as embodied a machine particularly adapted forall-round nailing in the manufacture of boots and shoes.

Machines used for all-round nailing in the manufacture of boots andshoes, or indeed for any nailing off the last in which it is desired toclench the nails upon the insides of the 1o shoes, are commonly providedwith a work support, for example a horn, having a clenching cavity inits work-engaging surface.

Such machines, while in the main satisfactory, make conspicuous markingson the ini5 soles of the shoes nailed upon them. Moreover, the clenchingof the nails is not always as perfect as might be desired.

It is an object of the present invention to provide afastening-inserting machine havao ing clenching mechanism organized toobviate the marking of the surface of the Work upon which the fasteningsare clenched and at the same time to clench the fastenings in a superiormanner. In the operation of the illustrated machine, this isaccomplished by providing an anvil having a curved surface arranged tostart the clench in a predetermined direction, after which the anvil ismoved in the direction of the clench so as to bring a fiat surfacebeneath the end of the nail upon which the clench is completed. At theconclusion of the clenching, the anvil is forced against the nail in thedirection of the length thereof so that the clenched end of the nail isa; sunk in the material of the work, the head of the nail at that timebeing backed up and supported by the driver of the machine. Thepartially clenched nail lying between the surfacerof the work and theanvil prevents objectionable marking of the work as the anvil is movedto bring its flat surface into clenching position and the subsequentmovement of the anvil in the direction of the line of drive sinks theclenched end of the nail in the substance of the work. and presents asmooth surface upon the inside of the shoe.

With the above and other objects and features in view, the inventionwill now be described in connection with the accompanying drawings whichshow a machine constituting Serial No. 81,430.

a preferred embodiment of the invention, and pointed out in theaccompanying claims. It should be understood, however, that the machinemay be modified in various'respects within the scope of the claimswithout departing from the invention.

In the drawings,

Fig. 1 is a side elevation, partly in section, of nail-inserting machineembodying the present invention;

Fig. 2 is a horizontal section on the line II-II of Fig. 1; and

Figs. 3, 4 and 5 are vertical sections through the upper portion of theWork-supporting horn of the machine and a work piece carried thereby,showing three different stages in the fastening-inserting operation.

The invention illustrated herein is embodied in a fastening-insertingmachine of the general type disclosedin United States Letters Patent N0. 1,030,775, granted June 25, 1912, on an application filed in the nameof George Goddu, the machine, however, being provided with work supportcontrolling mechanism of the type illustrated in United States LettersPatent No. 1,011,941, granted December 19, 1911, on another applicationof said George Goddu. In describing the present invention, it isunnecessary to set forth in detail the construction and mode ofoperation of many of the parts of the machine, and for a fulldescription of such parts reference may be made to said Letters Patent.

The illustrated machine is provided with a main frame or column 10carrying at its upper end a head 12 and with a secondary column 14carrying a work support, illustrated as a horn 16. The head 12 carries acam shaft 18 from which the various parts of the machine are operated,Among the parts operated by cam shaft '18 are the usual Workfeeding awl,a driver 20, and the work'su-pport controlling mechanism; Thev latter,as more fully set forth in said Letters Patent No. 1,011,941, includes aspring 164 arranged, through toggle mechanism 162, 17 0 and levermechanism 464, 468 connected to the horn shaft 22, to take up the thrustupon the work support 16 as each fastening is inserted. Pawl and ratchetmechanism 186, 190 is acranged to lock abutment 165, against which thelower end of spring 164 bears, against downward movement when toggle162, 170 is broken by link and lever mechanism 176, 178 to relievepressure upon the work during the feeding of the latter. In order toraise the work support to operative position, the machine is providedwith a treadle 3 which is pivoted to link 480, the upper'end of which isconnected at 490, by a joint permitting a limited amount of lost motion,to lever 478 fulcrumed at 47 4 to a downwardly extending fork member oflever 464. A cam 476 carried by lever 478 engages a roll 482 carried bylever 468. Lever 464, which is pivotally connected at 470 to lever 468and at 466 to toggle memher 170, is fulcrumed upon a shaft 458 supportedby column 10. Lever 468 is provided with a slot 486 through which shaft458 passes so as to permit a limited amount of relative movement oflevers 464 and 468, both the horizontal and vertical dimensions of slot486 being greater than the diameter of shaft 458. When treadle 3 isdepressed, lever 478 is rocked, causing cam 476 to lift roll 482 andlever 468, the latter rocking about pivot 470 until the work support 16has been lifted to bring the work into engagement with the presser plateof the machine. Thereafter, lever 468 is rocked about itsconnection withthe horn shaft, lever 464 rocking about its fulcrum 458, thus liftingthe rear end of lever 464 and, through toggle 162, 170, which at thattime is straightened, compressing spring 164.

' In the illustrated machine the horn 16 is provided at its tip withhorizontal ways 24 (Figs. 3, 4 and 5) in which is mounted for slidingmovement an anvil 26 provided at its left-hand end, as viewed in Figs.3, 4 and 5, with a curved surface 28 arranged to start the clenching ofthe fastenings and with a flat upper surface 30 upon which the clenchingis completed. Curved surface 28- is in the line of drive at the time thepoint of the nail breaks through the lower surface of the work as shownin Fig. 3, but immediately thereafter the anvil 26 is slid transverselyof the line of drive and in the direction of the clench, to the left asillustrated, so that the clenching is completed against the flat uppersurface 30 of the anvil as in Fig. 4. Mechanism for thus sliding theanvil will now be described. Mounted upon the cam shaft 18 of themachine is a bevel gear 32 meshing with a bevel gear 34 carried by avertical shaft 36. Shaft 36, at its lower end, carries a bevel gear 38meshin with a bevel gear 40 carried by a short sha t .42 journaled in astationary part of the machine and connected through universal joints44, 46 and a telescoping shaft 48 with a cam shaft 50 journaled in thelower end of a support 52 which support is mounted for sliding movementin ways 54 and in a bearing 56 carried by column 14. In the presentmachine the lever 468 is pivoted to the horn shaft support 52 instead ofdirectly to the horn shaft as in said Letters Patent previously referredto. The upper portion of horn shaft support 52 is formed with anelongated bearing for the horn shaft 22, the latter being made hollow soas to house a rod 60, the lower end of which is bifurcated so as tostraddle cam shaft 52. A cam roll 62 is mounted near the lower end ofrod and engages a closed cam track 64 formed in a cam member fast uponshaft 50. Thus rod 60 is raised and lowered at predetermined times inthe cycle of operation of the machine. Fulcrumed at 65 to horn 16 is alever 66, one end of which is connected by a pin and slot connection 68to the upper end of rod 60 and the other end of which is connected by apin and slot connection to the lower end of rod 70 (Figs. 1 and 3)mounted for vertical sliding movement in horn 16. The upper end of rod70 is connected by a pin and slot connection 72 to an inclined rod 74also mounted for sliding movement in horn 16 and connected by a pin andslot connection 76 with a link 78 pivoted at 80 to anvil 26 and formedwith a pair of horizontal guide surfaces 82, 84 bearing uponcorresponding surfaces formed toward the tip of the horn. This mechanismis such that when rod 60 is lowered, rod 70 moves upwardly, rod 74 movesupwardly and to the left, as viewed in Figs. 3, 4 and 5, and link 78moves horizontally to the left carrying anvil 26 with, it. Since roll 62runs in a closed cam track and since the driver 20 is operated from aclosed cam track, shown at 86 in Fig. 1, the movement of the anvil canbe timed accurately relatively to the movement of the driver.

After the anvil has been slid to the left to the position indicated inFig. 4 and the nail completely inserted, driver 20 is held momentarilyin engagement with the head of the nail, cam track 86 being suitablyformed for this purpose. At this time, before the driver is withdrawnfrom contact with the head of the nail, horn 16 is given a bodily upwardmovement so as to sink the clenched end of the nail into the substanceof the work, as shown in Fig. 5. This is accomplished by a cam surface88 formed upon a cam carried by shaft 50 and engaging the lower end ofthe horn shaft 22.

Since the direction of the clench, as determined in the first instanceby the curvature of surface 28, continues unchanged as anvil 26 is slidto complete the clench against flat surface 30, uniform clenching of thefastenings is insured. The movement of the anvil in the direction of theclench tends to wipe the end of the nail in the direction of the clenchand to prevent crippling of the nail. The partially clenched end of thenail between the surface of the work and the anvil prevents marring ofthe work by the anvil as the latter moves during the clenching and thesubsequent movement of the anvil toward Having described the invention,What I' clalm as new and des re to secure by Letters Patent of theUnited; States is:
